This week's Arcade Archives release is... Fighter & Attacker (Namco, 1992)... Or at least, it was supposed to be.
As has happened a few times with Namco games, this one has not been released outside of Japan, so the Japanese storefront links are provided below:
If you do go for the Japanese release, bear in mind only the Japanese ROM, titled F/A, is included.
This one stings a little- I was looking forward to giving this a try, and it's also the 10th anniversary celebeation game for Arcade Archives, so not being able to get it properly over here is a bit disappointing. It's also a notable title for never being given a home port until now and for having an absolutely incredible Shinji Hosoe and Takayuki Aihara soundtrack, so I'm sure a few people were looking forward to this. I was waiting on this release to dig into the game but, well, that didn't happen so, uh, you'll have to ask someone else about the game itself, I don't shmup so well. Fortunately, making a Japanese account for both PSN and Switch is fairly easy, and I've linked some guides (with pictures!) to help you out. Although the PSN guide is specifically for PS4 (could be worse, one of the guides I found used PS3 screenshots, whoof).
Now, in the past I've tried to avoid speculating on why this sort of thing happens with Namco games because I feel a little responsible for the perception around what happened with Marvel Land... This one, though, I can at least give a solid guess because it seems really obvious- Fighter & Attacker has 16 (!) playable aircraft based on real planes, including the F-14D Tomcat. Whenever Sega rereleases After Burner II, they have to get a license for using that plane from Northrop Grumman, so perhaps this made Bandai Namco baulk (and at this point it does really seem like them- it's almost always their games, and they seem really antsy about anything remotely copyright-infringey).
Fortunately, I know what you people want to hear.
OK, OK, just joking! I couldn't resist posting the iDOLM@STER remix. Here's the Fighter & Attacker soundtrack for you to enjoy~
Anyway, I know this is disappointing, but as a reminder, don't shoot the messenger. I've never had any luck in contacting Hamster myself (I've sent emails a few times about the dozen-or-so ACA games MIA on EU PSN) so I do wish they were more transparent, but you're better shouting at them, not me. I'm only little! You can't be mad at me!!

The conclusion of Namco Month is a doozy, almost certainly one of the most often-requested Arcade Archives rereleases based on how often it's come up in conversation, Namco's Numan Athletics is, in my estimation, one of the greatest Track & Field-style games ever made. Yes, there was a sequel, Mach Breakers, but I feel they're both as excellent as each other, and the first game just about pips past the finish line first for me. The super-human theme is such a perfect fir for a game like this, allowing for outrageous and over-the-top events but also keeping play very simple, focusing on button-mashing for events like the Turbo Dash and Non-Stop Rock Chop, timing and reaction like with Tower Topper, Interceptor and Numan Sniper, and a bit of both for Missile Toss, Vs. Express and Niagara Jump.
